SPECIFICATION forming part of Letters Patent No. 395,649, dated January1, 1889. Application filed December 27, 1887. 8erial No. 259,165. (Nomodcld Patented in England August 18, 1887, No. 11,310; in BelgiumAugust 18, 1887,1510. 78,611; in France August 18,1887, No. 185,389; inGermany August 18, 1887, No. 42,698, and in Austria-Hungary January 8,1888, No. 32,842 and No. 63,396.

1'0 aZZ whom it may concern.-

.llc it known. that I, JOSEPH IllAUsCHKE, a subject of the King ofPrussia, residing at .llreslau, in the Province of Silesia, in the 5Kingdom of Prussia and Empire of Germany, have invented a new and usefulImprovement in Illoiler-Cleaners, (For which the following patents havebeen granted to me and to my assignee, E. M. lIEIBER, to wit: ofBelgium,

No. 78,611, dated August 18,1887; of France, No. 185,389, dated August18,1887; of Germany, No. 42,693, dated August 18, 1887; of England, No.11,310, August 18,1887; of Austria--Hnngary, Nos. 32,812 and 68,896,January 8, 1888,) of which the following is a specification.

The nature of the invention consists in the combination, with anexterior cylindrical boiler supported above a furnace with its axis innearly a horizontal position and having in either end bearings, morefully hereinafter de. 'ribed, of an interior cylinijlrical boiler withinthe said cxteriorboiler and of such size as to allow for water and steamspace he- 2 5 tween the interior of the exterior boiler and the exteriorof the interior boiler, said interior boiler containing no water, butbeing adapted for the admission of steam, and being mounted uponjournals running in the bear- 0 ings aforesaid in the ends of saidexterior boiler, one of the journals of the said interior boiler beingprovided with a crank, by means of which. the said interior boiler maybeoscillated around its axis upon its said journals,

3 5 having a series of scrapers attached to the exterior of said innerboiler within said outer boiler, so that when the said inner boiler isoscillatei'l the scrapers, moving therewith, 0perate upon the innersurface of the bottom 40 part of said exterior boiler to remove thescdiment, scales, and depositions of feed-water.

The nature of the invention also consists in the details of constructionand combination, substantially as illustrated in the drawings,

4 5 herei n after described,and subsequently poin ted out in the claims.

Figure 1 is a vertical axial section of a boiler constructed accordingto my invention. vliig. 2 is a transverse section of the same. Figs. 3

and 1 are detail views of parts of the scraper,

more fully hmeinafter described. Fig. 5 is a diagrammatic view showinghow the device may be constructed to connect with a drivingpower.

A designates the exteriorboiler, which is to be placed upon its furnacewith one end alittle lower than the other. At either end arejournal-bearings 13 11, which may be made steam-tight with a convenientstuliing-box in any common and well-known way. This exterior boiler hasa steam-outlet at its top, (designated by O which maybe of any commonand well-known form. \Vithin this exterior boiler, A, is an interiorboiler, 0, having its axis coincident with the axis of the boiler A andniountcal upon journals which work in the bearings ll 3. The journalwhich works in the bearing B may be provided with a lever or a winch, asD, by means of which the boiler (1 may be oscillated around its axis, as

illustrztted in Fig. 5, either by being attached to a driviug-power oriuany other convenient way. Between these two boilers there is a spacesul'ii out for the reception of water and the generation of steam.

The boiler is not to contain water, but is perforated on its upper sideat 0, through which the steam is free to pass in and out.

In order to draw off any water that may arise from the com'lensation ofsteam in said. boiler C, the siphon-tube 8, pa ng through the bearing at13, has been provided. This tube has a stop-cock, to close its end, at71.

To either end of the interior boiler is attached a bearing at c, inwhich the rod (Z is set parallel to the axis of the boilers. Upon thisis mounted by itsmiddle the lever 0, upon either end of which is mounteda triangular bar, (1, parallel to the rod d, and with its edge nestingon the inside of the boiler A. This rod a is held in place by thebearings Z2, and is notched atu, so that it will not catch on the rivetson the inside of the boiler A. At the lower part of the boiler is anoutlet-pipe, F, connecting by means of the slide-valve G with 5 the bulb11. This bulb 11 connects with a waste-pipe which is opened and closedby tn r1 1.- ing the valve J, the whole device to b as illustrated inthe drawings.

It is a well-known fact that water used to feed a steam-boiler depositslime and other earthy and mineral substances in the boiler in thegeneration of steam, and that these deposits adhering to the interiorsurface of the boiler give great trouble and annoyance to the operator.I obviate this as follows: 'When the boiler is in use, the oscillationof the interior boiler carries with it the scrapers a and theiraccoi'npanying mechanism. The sharp edge a, scraping on the inside ofthe boiler A, keeps the sediment in the inside of the boilerA constantlystirred up, and that sediment making its way downward graduallyaccumulates over the outlet-tube F. It the slide-valve (t is opened andthe valve .l closed, it gradually falls in to the bulb I'll. \Vhen thisbulb is't'ull, the valve G may be closed andJ opened. Then the sedimentrunning out of the bulb II cscapes through the waste-pipe, and thus Iclean the sediment and scales out of a boiler without withdrawing thetire or decreasing the head of steam.

hat I claim as my invention, and desire to secure by Letters Patent, is

1. The combination, with an exterior cylindrical boiler supported abovea furnace with its axis in nearly a horizontal. position, and having ineither end bearings, substantially as specified, of an interior.cylindrical boiler within said exterior cyliiulrical boiler and of suchsize as to allow for water and steam space between the interior of theexterior boilerand the exterior of the interior boiler, said interiorboiler to contain no water, but being adapted for the admission ofsteam, and being mounted upon journals moving in the bearings aforesaidin the ends of said exterior boiler, one of the journals of saidinterior boiler being provided with a crank, by means of which the saidboiler may be oscillated around its axis upon its said journals, havinga series ot scrapers attached to the exterior of said inner boilerwithin said outer boiler, so that when the said inner boiler isoscillated the scrapers moving therewith operate upon the inner surfaceof the bottom part of the said exterior boiler to remove the sediment,scales, and depositions of feed-water there from, substantially as andfor the purpose set forth. I

2. In a steam-generator, the combination, with the exterior boiler, A,having-bearings B B, outlet-pipe F, valve G, and bulb H, having awaste-pipe closed with a valve, J, of the inner boiler, U, journaled insaid. boiler A at Y) and B, having the winch I) attached to one of itsjournals, and the siphon-pipe S, passing from within through one of itsjournals and closed without by the cock h, the bearings 6, attached tosaid inner boiler, the rod din said bearings, the arms c, mounted onsaid bar (I, and the scrapers a, ll'lOlllltlGtl upon said arms 0, tooperate upon the interior of the said exterior boiler, A, substantiallyas and for the purpose set forth.

, In testimony whereof Ihereunto sign my name, in the presence of twosubscribing wit,- nesses, this lst day of December, 1.887.

JOSEPH BAUSCHKE.
